WEBER, or CHICAGO, rrtnvorsf'assreiron ro AMER CAN-nutrit onal) PAPER COMPANY, or AT'ILEBORO, MAssAcHUsETrs, A coeronarroiv out/Lassa cnusa'rrs TARrAULI v This invention relates to tarpaulins or waterproof sheets adapted for use as acovering for various objects to protect them from the weather. a

Tarpaulins as commonly constricted are formed of canvasthat is treated to render the same waterproof, and are employed to cover and protect various objects on land and aboard ship but the canvas required to make a tarpaulin is relatively expensive.-

" The, present invention therefore relates to a modified tarpaulin or covering sheet formed of reenforced waterproofed paper, and this modified tarpaulin may be given any desired width by adhesively securing or otherwise fastening two or more strips ofireenforced paper together.

The paper employed in forming the=tar paulin of the present invention may be variously reenforced with either spun or unspun fibres and variouscoating materials may be employed to render the paper waterproof, but a good practical construction is secured by adhesively securing unspun fibres of long staple between two sheetsof paper, and'the fibresare preferably laid bothlongitudinally and transversely of the paper to reenforce the with tie loops placed along the edges of the tarpaulin to receive'a rope or other means for securing the tarpaulin' in place over the object to be'protected, and it is desirable to provide the modified tarpaulinor cover of the present invention with similar tie loops. The tieloops are usually sewed to the canvas tarpaulin but it is not desirable to sew the tie loops to the reenforced paper of the present modified tarpaulin, since the perforations.

formed in the paper by the sewing machine needle will decrease the strength of the paper.

, 7 One important feature of the present invention therefore resides in a reenforced paper tarpaulin or cover having the tie loops adhesively secured to the edges of the reenforcedrpaper so that a strong pull exerted on the tie loops will be transmitted to the paper without tearing the latter and in means for excluding moisture from the portions of the tie loops secured to the-paper. r

which illustrate one 7 While various forms ofzfibres may A furtherimportant feature of the present v invention resides' in a tie loop having the leg portions of the loop firmly securedtogether close to the edge of thereenforced paper so that .a pull exerted upon either leg of the tie loop will be transmitted directly to the other leg'at the edge of the paper to prevent the leg portions of the tie loop from -being pulled loose from the paper by a s'train'exerted later ally'to the plane of thepap'er. I

- Still -a-further feature of the invention resides in a reenforced papertarpaulin having its marginal edges folded over and sealed. 1

to the face of the paper to prevent the edge from tearing. I v V The above and otherfeatures of the invention will be: hereinafter described in connection 'withthe' accompanying drawings good practical form of the invention. r 1 1 Inthe drawings: v Fig. 1 is a plan view of part of a reenforced paperfltarpaulin and tie loopembodying the features of-the present invention;

- Fig. 3, on a reduced scale, is a plan view of a-corner portion of the tarpaulin of the present invention; w r Fig. 4 is a plan View of a modified form of a reenforced papertarpaulin; and 1 Fig.5 is a sectional view takenvon the line *55 of Fig. 4. 1 The reenforced paper employedin constructing the tarpaulin-or'cover lof the r present invention may be variously constructed but is shown in the drawings as formed of two sheets of paper Q'and 3 having secured between themthe layers 4 and 5, of relatively straight unspun fibres, one layerof fibres being positioned transversely .of the paper and the other layer longitudinally of the paper as shown in Fig.1.

v be employed to reenforce the paper sheet 1', a strong'and desirablepaper isproduced by employing fibres of long staple such as sisal as the "reenforcing elements and these fibres are preferably secured to the paper in a straightened condition as shown. Different 1 is important, and in the embodiment of the.

"of the'sheet 1. v

waterproof adhesives may be employed 0 paulin of the present invention maybe given any desired size by varying the width of the reenforced paper of which it is Constructed, or by securing two or more strips'of paper together. Only a small portion of the entire tarpaulin has been shown in Fig. 3 of'the drawings. 7 1 It is lm-portant to provlde anchoringlmeans at spaced intervals alongthe: edges of the tarpaulin so that thetarpauli-n-may be tied in place over the object to be protected, and this is accomplished inaccorda-nce' with the present invention by providingv the as loops 6 at spaced intervals along the sides and. ends 7 These tie loops or strips 6 are conveniently formed of woven; fabric,'but the manner of securingv them. to the paper so as tOaPIOdllCfia. strong-anchor whichwill not tear the paper invention illustrated each tie loop 6 .has the end portions of its legs 7 and- 8 adhesively secured tothe op osite-faces ofthe reen'forced sheet. 1. To furt er strengthen'the construction, afprotecting and. strain distributing patch 9 which may be constructed of-"reenforced waterproof paper similar to the sheet 1, is'adhesively secured over they-end portion of each leg 7 and 8, as will be apparent from the: drawings. Theipatches 9 are preferably made. relatively large as-shown to help distribute the, pull exerted .by'each tie loop over a comparatively large area of the sheetvll and toexclude moisture from the portions of the-tieloop secured-to the: sheet. The adhesive used for securing the: endsof the tie loop 6 to' the paper 1 and for securing the patches. 9 over these end portions may be the same as that employed between the sheets 2 and 3, or any may be employed.

While the construction so far described for securing thet-ie loops 6 to the paper 1', will withstand astrong straightpull upon the loops,- a: pull exerted upon a legof the loop laterally to theplaneof the paper will tend to pull the same loose from the face of the paper to" which it is secured; In order to prevent this'the legs'7' and 8- are firmly secured together at the. edge of the: paper to prevent. separation of the legs at this point. This is conveniently accomplished by sewing the legs hand 8 together, close to; the edge of the paper with one or more rows of stitches'lO; Y

The strength and durabilityof aatarpaulin formedl of reenforced paper may be further other strong durable adhesive increased in accordance with the present invention by folding the marginal edge portions of the reenforced paper over as indicated by 11 and adhesively securing these folded portions to the face of the sheet as shown in Fig 4:. It may also be desirable tofold the corners inwardly as indicated by 12 and adhesivelysecure these corners to the face of the fabric. V .When the edge portions 11 and" corners 12 are folded inwardly the anchoring loops 6 are. preferably secured to these folded portions as clearly shown in Figs. and 5, as this will further prevent these loops or straps from teari ng'the paper.

It will-be seen from the foregoing that the reenforced paper tarpaulin or cover of the present invention may; be employed in various industries where a relatively large,

water proof covering is desired andthat the sameis sufficiently strong and durable'to give good service, while the cost of this reenforced papertarpaulin is-only a fraction of. the cost of a tarpauli-nformed ofcanvas.
